If there is an injury or lesion in the lumbar spine or around the lumbar spine, the location of the poultice should be chosen based on the injury or lesion, or the location of the pain. If the ligaments between the lumbar vertebrae are chronically injured, the poultice will be chosen to be applied to the location of the pain, which can have a therapeutic effect on the local area, and can also relieve the local pain. If the soft tissues around the lumbar vertebrae, such as the muscles of the lumbar region have chronic strain injury, the plaster will be applied to the location where the localized pressure pain is most obvious, in order to be able to play a more significant effect. In the case of the third lumbar transverse syndrome, the plaster should be applied to the location of pain near the lumbar spine, which can improve the inflammation of the soft tissues in this location. However, if the lumbar spine itself has a disease such as lumbar disc herniation, you can only apply the ointment to the location of the lumbar disc herniation, but the effect may not be too ideal.
